| Application: | Lanthanum(III) oxide can be used as a dopant to prepare radiation-shielding glasses. For example, it can be added to waste soda-lime glass to improve the linear attenuation coefficient and radiation shielding characteristics of the glass. It can be used as a recyclable catalytic system for the synthesis of diphenyl sulfides and selenides and for the C-N cross-coupling of aryl halides with heteroaromatic amines. It can also be used as a promoter or support material for the selective oxidation of methanol over gold catalyst. |
| Application: | Precursor to LAMOX fast ion conductors and superconductors. |
| Features and Benefits: | • High refractive index • Low dispersion • Colorless in the glass matrix • Efficient, inexpensive, and recyclable catalyst |
| General description: | La2O3 is a wide band gap p-type semiconductor with an empty Ln-4f shell and is widely used to prepare optical materials, dielectrics, and conductive ceramics. La2O3 can also be used as a catalyst in many organic transformations. |
